Temporalis Tendon Transfer/Lengthening Temporalis Myoplasty for Midfacial Static and Dynamic Reanimation After Head and Neck Oncologic Surgery

Facial Reanimation and Reconstruction of the Radical Parotidectomy

Radical parotidectomy may result from treating advanced parotid malignancies invading the facial nerve. Survival is often enhanced with multimodality treatment protocols, including postoperative radiation therapy. In addition to the reconstructive challenge of restoring facial nerve function, patients may be left with a significant cervicofacial concavity and inadequate skin coverage. This should be addressed with stable vascularized tissue that is resistant to radiation-induced atrophy. This article describes a comprehensive strategy, includes the use of the anterolateral thigh free flap, the temporalis regional muscle transfer, motor nerve to vastus lateralis grafts, nerve to masseter transfer, and fascia lata grafts for static suspension.

Smile Outcomes of an Externally Scarless, Intraoral Orthodromic Temporalis Tendon Transfer

Background: Temporalis tendon transfer (TTT) often relies on external incisions in the nasolabial fold, temporal region, or both. Herein, we studied smile outcomes of a TTT technique via a single intraoral incision without external skin incisions. Objective: To measure the difference in static perioral positions before and after intraoral TTT. Methods: Five patients underwent an externally scarless TTT technique via an intraoral approach. Iris measurements were used to estimate pixel-to-millimeter conversion for facial analysis of vertical and horizontal oral commissure excursion vectors using the JAVA-based program Facegram version 1.0 (Massachusetts Eye & Ear Infirmary). Results: After surgery, mean vertical height on the affected side significantly increased from 3.4 mm to a postoperative value of 20.6 mm, p = 0.016. There was no difference in horizontal smile excursion after surgery (35.7 mm vs. 32.2 mm, p = 0.37). Smile angle difference between affected and healthy smile (Δα) reduced from 27.0° preoperative to 3.5°, representing a decrease in facial asymmetry (p = 0.002). Conclusion: Intraoral, externally scarless TTT is an effective option for dynamic facial reanimation, obviating external incisions in select patients.
